LIGHTING FIXTURE Filed Oct. 18, 1928 Patented May 19, 1931 UNITED STATES isaazsi REUBEN HALEY, OF BEAVER, PENNSYLVANIA LIGHTING FIXTURE Application filed October 18, 1928. SerialNo. 313,273.

My invention relates to lighting fixtures, and has for an object the production of an upper transparent lamp enclosing member, a lower translucent light diffusing shade or bowl, and novel means for detachably connecting these elements, as also means for securing the fixture in operative position to a ceiling or other point of support.

As a further object this invention is designed to furnish a two-piece, all glass fixture capable of being quickly assembled, and when required, as readily disassembled, as for example, when it becomes necessary or desirable to remove or replace an incandescent lamp bulb.

A further object is that of producing a twopart lighting fixture which is extremely simple in construction, attractive in appearance, and efficient in operation.

A further-object is the production and combination of separable units in a two-piece glass lighting fixture, which will not become inoperative by reason of overheating.

With the foregoing and other objects and advantages in View, the invention will be hereinafter particularly described and pointed out' by the appended claim.

In the accompanying drawings which form part of this application, and whereon like reference characters indicate corresponding parts in the several illustrations:

Figure 1 is a side elevation of a lighting fixture with its shade or bowl unit shown in section;

Figure 2 is a view of the two-part glass fixture taken on the line 22 of Figure 1;

Figure 3 is a fragmentary view in side elevation showing lower part of the lamp enclosing member and one of several lug admitting notches; and

Figure 4 is a horizontal section through lower end of the lamp enclosing member taken on the dot and dash line 4 t of Fig ure 2.

Reference being had to the drawings and numerals thereon, 1 indicates an ordinary shade holder which is usually secured in fixed relation to a ceiling or other suitable support as indicated at 2. This holder is ordinarily be made of spun'brass, but may be formed of porcelain,glass or any other suitable material, and is designed to receive a transparent, glass upper lamp enclosing member 3, within which, as usual, is located anordinary electric lamp 4.

The unit 3 may be either a reflecting or defleeting element, and may be variously ribbed or otherwise configured upon its surfaces, but in any event, is preferably substantially cylindrical in form and is at its base provided with an integral peripheral down wardly and outwardly beveled flange 5 broken at intervals by lug-admitting notches G, 6, 6, as best shown by Figure 2.

This flange 5 is also configured by extended depressions 7, 7, 7, upon its upper surface in termediate the notches 6, 6, 6, aforesaid for purposes which will later appear.

The numeral 8 indicates a shade or bowl which may be variously ornamented, and of any exterior shape or configuration, but of hollow or concave form, and provided at equidistant points with integral lugs 9, 9, 9, converging toward the shade center. The lugs 9 are arranged and adapted to freely enter the notches 6 aforesaid of the reflecting unit 3, and when so entered the shade member 8 may readily be rotated axially until said lugs interlock with the radial flange 5 of the relatively fixed unit 3, as shown by Figures 1 and 2. When in the latter or detachably interlocked position, the attaching lugs 9 rest normally in the depressions 7, and are restrained against accidental dislodgment by the risers or slight shoulders 10 at each end of each depression 7, over which latter however the lugs 6 easily ride when rotary force is applied to the shade unit for the purpose of removing same.

This being a description of my invention in one form of embodiment, its use and operation are so obvious as to hardly require description. It will be noted however, that the holder 1, the member 3, and its contained lamp 4, are secured in position to a ceiling 2, or other support, in the usual way as indicated by Figure 1 of the drawings. When however, it is desired to add the depending shade or bowl element 8, this is quickly and securely accomplished by passing the internormal operative position shown by Figure I looking lugs 9 through their respective lugreceiving notches 6, and rotating the shade 8 partiallyto interlock them with the base flange 5 surrounding the loweredge of the member 3, During this process the lugs 9 first ride down the shoulders 10 continuing along their respective elongated depressions 7 to intermediate positions thereonQ V To instantly remove the shade 8, for purposes of cleaning,repairs or replacement, a reversal of the operation aforesaid is obviously sufficient, and When shade 8 is in its 1, it is quite secure against accidental dislodgment. On the other hand, if the combined fixture is in service where there is an unusual amount of vibration as for example, railway cars, or marine vessels, Which might possibly cause lugs 9 to travel along the depressions 7,-their limit of movement vvould be p the shoulders 10 at each end of said depressions by which further movement of the, lugs Would'be" arrested. i

' Hav'ingthus described my invention What I now'claim and desire to'secure by Letters Patent,is:. i

' A two part lightingffiztture comprising a lamp enclosing-memberof substantially cylindrical form, a concave open bowlmember of greaterdiameterthan the lamp enclosing member and having a free'redge extending substantially midway the heightof the lamp enclosing member, and means for securing saidlamp enclosing member and said-bowl together. 7 A r In testimony whereof I afliX my signature.
